# 1、建立模板项目 #

├─.settings  
├─demo-core  
│  ├─.settings  
│  └─src  
│      ├─main  
│      │  ├─java  
│      │  │  └─com  
│      │  │      └─test

# 2、生成模板骨架 #

## 2.1 安装本地仓库 ##

进入多模块项目根目录，执行如下命令

>mvn archetype:create-from-project -Darchetype.filteredExtensions=java
    > cd target/ #进入target
    >tree
    generated-sources
        └─archetype
            ├─src
            │  ├─main
            │  │  └─resources
            │  │      ├─archetype-resources
            │  │      │  ├─.settings
            │  │      │  ├─__rootArtifactId__-core
            │  │      │  │  ├─.settings
            │  │      │  │  └─src
            │  │      │  │      └─main
            │  │      │  │          └─java
            │  │      │  │              └─core
            │  │      │  └─__rootArtifactId__-db
            │  │      │      ├─.settings
            │  │      │      └─src
            │  │      │          └─main
            │  │      │              └─java
            │  │      │                  └─db
            │  │      └─META-INF
            │  │          └─maven
            │  └─test
            │      └─resources
            │          └─projects
            │              └─basic
            └─target
                ├─classes
                │  ├─archetype-resources
                │  │  ├─.settings
                │  │  ├─__rootArtifactId__-core
                │  │  │  ├─.settings
                │  │  │  └─src
                │  │  │      └─main
                │  │  │          └─java
                │  │  │              └─core
                │  │  └─__rootArtifactId__-db
                │  │      ├─.settings
                │  │      └─src
                │  │          └─main
                │  │              └─java
                │  │                  └─db
                │  └─META-INF
                │      └─maven
                └─test-classes
                    └─projects
                        └─basic
    >cd generated-sources/archetype/
    >mvn clean install #安装到本地仓库

## 2.2 安装到私服 ##

# 3、使用 #

## 3.1 本地使用 ##

>cd /tmp #代码生成目录
    >mvn archetype:generate -DarchetypeCatalog=local #从本地仓库选择模板

# 3.2 私服使用 #

>mvn org.apache.maven.plugins:maven-archetype-plugin:2.4:generate  
    -DarchetypeCatalog=http://ip:port/nexus/content/repositories/releases/ 
    -DarchetypeGroupId=demo-parent #私服上的groupId
    -DarchetypeArtifactId=demo-archetype #私服上的artifactId
    -DarchetypeVersion=1.0.0 #私服上的版本号
    -DgroupId=com.test #项目的groupId
    -DartifactId=demo.project #项目的artifactId
    -Dversion=1.0.0 #项目的版本

# 4、注意 #

第2步生成骨架-多模块项目-子模块的名不可以随便取，否则不能生成变量的项目。

子模块命名：父项目artifactId+子模块名。如父项目artifactId是demo，子模块demo-core。

下面为**maven-archetype-plugin插件的部分源码，可以看出子模块命名规范。**

for (Iterator<String> modules = pom.getModules().iterator(); modules.hasNext();) {
    	String subModuleId = modules.next();
    
    	String subModuleIdDirectory = subModuleId;
    
    	if (subModuleId.indexOf(rootArtifactId) >= 0) {
    		subModuleIdDirectory = StringUtils.replace(subModuleId, rootArtifactId, "__rootArtifactId__");
    	}
    
    	createModulePoms(pomReversedProperties, rootArtifactId, packageName,
    			FileUtils.resolveFile(basedir, subModuleId),
    			FileUtils.resolveFile(archetypeFilesDirectory, subModuleIdDirectory), preserveCData, keepParent);
    }

# 5、导入eclipse #

window->perferences->maven

私服的archetype-catalog.xml

新建maven项目时，选择“demo”即可看到我们自己的模板了
